CHARLES MULDNER, OF CLEVELAND, OHIO.

'CARPET-RENOVATOR.

SPECIFICATION forming part of Letters Patent No. 267,917, dated November 21, 1882.

.Application filed June 16, 1882. (No model.)

To all whom it may concern:

Be it known that I, CHARLES MULDNER, of Cleveland, in the county of Guyahoga and State of Ohio, have invented a certain new and Improved (Jarpet-Renovator and I do hereby declare that the followingis a full, clear, and complete description thereof.

The nature of my invention relates to a carpet-renovator and it consists of a lagged or grated cylinder with openings between the said lags, and the interior provided with spiral longitudinal ribs or wings projecting from the interior surface of the cylinder. The cylinder is mounted in a frame upon journals, for its rotation by any suitable motor. 7

i That the invention may be more fully understood, reference will be made to the following specification and to the annexed drawings, making part of the same, in which- Figure 1 is a side view, and Fig. 2 a transverse vertical section in the direction of the line am, Fig.1.

Like letters refer to like parts in the several views.

The frame A may be of any suitable construction for the purpose of supporting the grated cylinder B, which cylinder is made up of lags and two solid, or entire heads, 0 O, to which are securely nnected the journals or gudgeons D D, Fig. 1, to one of which are attached the driving-pulley Eand loose-pulley F, provided with a belt for rotating and stop ping the cylinder. To the periphery of the heads are secured the lags G, with a'space, H, between for the escape of dust and dirt from the agitated carpet. Thus the entire circle of the cylinderis made up of lags with intervening spaces. In the interior of the cylinder, and secured to the inside face, are ribs or wings I I I". These ribs may project more or less from the interior face of the cylinder in radial lines, as seen in Fig. 2, and they may be arranged to be in alignment with the cylinder, or in a diagonal or spiral line, as indicated at I .5 I, Fig. 2, and by the dotted lines 1 I in Fig. 1. The spiral or diagonal positions of the ribs 1 I" are arranged in opposite directions,'f0r a purpose hereinafter set forth. The entrance to the interior is through a door, J,.which is 50 hinged at KK and provided with a removable fastening at L, Fig. 1. By means of this door the carpets. are placed in and withdrawn from.

by the wings or ribs and as constantly sliding of and falling back.' This operation of raising up the carpet and of its falling back is as'continuous as the rotation of the cylinder. By means of the oblique or diagonal position of the wings I the carpet is conveyed in a lateral direction while it is being agitated by the rotation of the cylinder and wings. The wings I I are placed in the interior of the cylinder in such relation to each other that one of the said wings or ribs, I, will cause the carpet to be directed longitudinally in the cylinder in one direction, while the other wing, I", will cause the carpet to be moved laterally in an opposite direction. By this means the carpet is subjected to compound movement by the action of the wings I and lateral or longitudinal movement caused by the ribs I I. In this way a continuous agitation and beating of the carpet is maintained, thus causing the carpet to beconstantly unfolding, and exposing it in all parts to the renovating and cleaning action of the ribs as they revolve. The cylinder is designed to be from ten to fifteen feet in diame ter, more or less, as may be required for the work.

The falling and rolling motion of the carpet from the wings as they rise onto those below produces an action not unlike that of shaking and beating out the dust and dirt, so as to completely renovate it without tearing or other injury. The dirt and Qdust, as it escapes from the carpet, passes away out of the cylinder through the spaces between the lags, and is accelerated by the wings in the cylinder, which act as-rotary fans in driving out the dust as fast as it is removed from the carpet. In this way the wings have a purposethat of agitat- I ning or driving out the dust from the cylinder.

ing and renovating the carpet, and also for fanthe entire interior face of the cylinder in op- [c l posite directions to each other, and provided What I claim as my invention, and desire to l with a door opening into said cylinder. secure by'Letters Patent, is- In testimony whereof I affix my signature in In carpet cleaning machines, the grated cylpresence of two witnesses.
